Product Description

The BMR RB003R Control Arm Reinforcement Braces are engineered specifically for 1978-1987 GM G-Body vehicles (such as Buick Regal/Grand National, Chevrolet Monte Carlo/Malibu, Oldsmobile Cutlass, and Pontiac Grand Prix). Factory stamped steel frame sections around the rear control arm mounts can flex under heavy acceleration, cornering, or launch conditions. These reinforcement braces tie the upper and lower mounts together with strong 1.0" DOM steel tubing to reduce mounting deflection and help maintain rear suspension geometry for improved traction and handling.

Finished in a corrosion-resistant red powdercoat, the RB003R braces bolt directly into place without drilling or fabrication, and provide extra clearance for mufflers and exhaust systems. Installation is typically completed in 2-3 hours with common hand tools. This upgrade is ideal for enthusiasts seeking to reduce wheel hop, enhance cornering consistency, and improve overall chassis response in street performance or racing applications.
